DELIVERY MECHANISM FOR STEREOTYPE-PLATE TRIMMING, GROOVING, AND SHAVING MACHINES.

SPECIFICATION forming part of Letters Patent No. 465,352, dated December 15, 1891.

- Application filed May 23, 1891.

Serial No. 393,838. (No model.)

Be it known that I, JOHN RAYMOND CUM- MINGS, of Chicago, Cook county, Illinois, have invented certain new and .useful Improvements in the Delivery Mechanism for Stereotype-Plate Trimming, Grooving, and Shaving Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The object of my invention is to improve on the delivery mechanism for my stereotypeplate trimming, grooving, and shaving machine for which I applied for Letters Patent of the United States on or about February 24, 1891, Serial No. 382,386.

The nature of these improvements is such that the complete and finished stereotypeplates are piled up in stacks of six each and then pushed to one side on suitable tracks or guide-frames, from whence they can be easily sents the said carrier.

removed, substantially as hereinafter fully described, and as illustrated in the drawings, in which Figure 1 is a plan view ofthat end of my improved machine in which my invention is located. Fig. 2 is an elevation of the contiguous end of the machine. Fig. 3 is a plan View of the same with the top of the tableframe and superstructure removed; and Fig.

l is a transvese vertical section therethrough,

taken on line 4 4:, Fig. 1.

Reference being had to the drawings, A represents the supporting-frame of my machine; B, the bed,which is inclined at a suitable plane toward the carrier, and C repre- As fully explained in the application hereinbefore referred to, the carrier receives the stereotype-plate from the feed-racks at one end of the machine, carries it to and past the cutting-tools, and then when it has reached the limit of its forward movement leaves the completed stereotype lying upon the bed while it makes its return movement. The finished stereotype-plate is held in the position in which it was left until the carrier has nearly reached the limit of its return movements, whereupon it is released, so that it slides laterally down the inclined surface of the bed to and through a longitudinal opening a at the foot of the same onto the ways Z). The incline of these ways I) b at their upper end is the same as and is a continuation of the plane of the bed B. Theirincline.

gradually changes to an easier slope as their lower angle b is approached, so as to slacken the speed of the plate gravitating down the same, and from their angles they pursue a perpendicular downward course, so as to form a guard, which keeps the stereotype from rebounding out of register, with the plates in its pile, as will hereinafterappear. As the stereotypes slide off the ways 1) they are deposited upon the platforms 0 c and are prevented from moving 01f the same by the perpendicular gage-bars d d, securedv to and depending down from the under surface of the top of the frame A, as shown. There are two of these platforms so locatedon the outside of the transverse plane of said ways that the ends only of the stereotype rest thereon.

The plane of these platforms'is just below that of the angle 17 of the ways 17, and when said'platforms c are reciprocated toward and past said gage-bars d the, stereotype, being preventedby said bars 1 from reciprocating with saidplatforms, is pushed off the same andfalls onto the sub-platforms c c. From these platforms, as the said platforms return to their normal positions, the stereotype is deposited onto (drop-platform e by striking I against the perpendicular port-ionof ways If.

Platforms c are each made by bending horizontally a suitable portion of the lower edge of the vertical sheet-metal guards f, which prevent longitudinal displacement of the stereotype'deposited on said platforms 0, and

Bars g g are reciprocated through the 1nedium of the arms 7676,110 the free ends of which they are pivotally connected, and the said arms project downwardly from a longitudinal ment, is met and pushed sidewise by the cam orbeveled edge of the extension 0" on the forward end of the carrier. Thus it will be observed that every time the carrier approaches the limit of its forward movement the rock-shaft is turned, causing arms 7r k to push bars 9, guards f, and platforms 0 c forward until the stereotype,having no support, falls onto sub-platforms c and from thence, as the platforms return to their normal position, onto the drop-platform below. When the carrier starts on its return movement, the rockshaft and devices actuated thereby, including the platforms 0, are automatically returned to their original positions by means of the coil contractiomspring s, which connects arms 70, or one of them, to a strap or cross-frame 6. These frames t are somewhat L- shaped, are connected at one side to the side rail of'supporting-frame A, and assist in the support of the operative devices of my invention. The platforms 0 are returned to their normal positions in sufficient time for the next stereotype to be received thereon. This, however, does not take place until the carrier has almost reached the limit of its return movement.

As before stated, the stereotypes are delivered onto the platforms 0 and from them drop to the drop-platform c. This drop-platform in its normal position is above the plane of the bars 9 and is secured to and supported in such position by the levers D D. These levers are fnlcrumed at their opposite ends to suitable lugs projecting from the vertical parts of the cross-frames t t and are supported at about their centers of length on the rollers E, journaled in the extremities of arms F F, which project in an upward position from the rock-shaft G. This rock-shaft G is journaled in suitable bearings on the horizontal stretch of frames 25. It has about its center of length, or midway between frames 25, an arm 11, projecting in an opposite direction from arms F, which are weighted in any suit able manner, but preferably by a rope or wire, or rod 1, depending down therefrom with weights J on its end. Thus when a number of stereotypes have dropped, one on top of the other, on the drop-platform sufficient to overcome the weight of weights J, said platfor-m moves downward until the ends of the stereotypes rest on frames 75 25. They remain in this position until the next reciprocation of the bars 9 g, whereupon the upturned ends K of said bars push them off said drop-platform (which the drawings will show to be of a length corresponding to the distance between frames 13 25) onto the tracks L L, which are a continuation of frames t, andlead transversely away from said drop-.platform' to the other side of the machine, from which the stacks of stereotypes can be easily removed ready for boxing and shipment. The moment the drop-platform is relieved of the weight of the accumulated stereotypes it rises to its original position and until the arm H, which is of sufficient length, bears against and is stopped by the frame A, as shown.

What I claim as new is- 1. In a stereotype-finishing machine, the combination, with a supporting-frame having an inclined bed and having a longitudinal opening in its top at the base of said bed, and a longitudinal reciprocal carrier 0, as described, of the inclined ways I) 1), leading down from said bed, the gage-bars cl opposite the lower ends of said ways, and the trans- VGISBlYrIGClIJIQCEtl platforms 0 c, as set forth.
